How to convert JPG to PNG
- Add your JPG files. Drop them anywhere on the page, or click the box and choose them. You can add a whole folder's worth at once.
- Press Convert. There is nothing to set: PNG is lossless, so there is no quality slider. Each row shows the JPG size and the PNG size when it is done.
- Download with the link on a row, or use Download all as ZIP for several files.
Each result keeps the original name with a new ending, so photo.jpg becomes photo.png. Your JPG files are never changed or removed.
What a PNG copy does not do
This is the most common misunderstanding, so it comes first. Converting a JPG to a PNG does not make the picture better. A JPG has already thrown away some detail, and that detail is gone for good. The PNG is a perfect copy of the picture as the JPG shows it, including any blockiness, blur or speckles, so it looks the same, and the file is much bigger. It cannot add back what was lost, and it does not sharpen anything.
If the goal is a sharper or larger picture, look at the image upscaler, which does add detail, with the limits described on its page.
Why the PNG is so much bigger
PNG keeps every pixel. A JPG keeps an approximation that takes a fraction of the space. We measured it on our own pictures:
| The JPG | The PNG from this page | Times bigger |
|---|---|---|
| 1024 × 768 photograph, 155 KB | 1,251 KB | about 8 |
| Photo as a lossy WebP, 63 KB (for comparison) | 966 KB | about 15 |
A photograph is the worst case, because it has millions of slightly different pixels. Keep that in mind when you convert a whole folder: a ZIP of PNGs can be ten times the size of the JPGs.
The size also depends on the program that writes the PNG. A browser's built-in PNG writer, which this page uses, does not try very hard to compress. On a screenshot-style test picture it produced 156 KB, while a more thorough encoder produced 93 KB for the same pixels. If you need the smallest possible PNGs, run the result through a PNG optimizer afterwards.
When a PNG copy is worth making
- You will edit the picture several times. Each time a JPG is saved again it is compressed again, and the damage adds up. Work on a PNG copy and no further loss happens, then make a JPG at the end. See PNG vs JPG vs WebP for the reasoning.
- A program or website wants PNG. Some design, game and dataset tools accept PNG and not JPG.
- You are preparing a cut-out. The background remover and the object cut-out produce transparent PNGs, and PNG is the format that keeps the see-through areas.
- You need an exact working copy that will not change if a program re-saves it.
If you only want a smaller or more compatible file, a JPG is the better choice and there is nothing to convert.
What is kept and what is not
- Pixel size and rotation. The picture keeps its full width and height, and the rotation tag that phones write is applied first, so the PNG is upright. We tested it: a 400 × 300 JPG tagged as rotated came out as a 300 × 400 PNG.
- Camera details and location. The date, camera settings and GPS location stored in a JPG are not copied to the PNG. That protects your privacy when you share the result, and it means photo libraries that sort by the date inside the file will not know when it was taken. See our EXIF guide, or use the metadata viewer to see what a file holds.
- Transparency. A JPG has none, so the PNG is fully solid. To make part of it see-through, use the background remover.
- Color profiles. An embedded color profile is not carried over, so pictures in a wide-gamut space can look slightly different.
Limits
- Browsers will not draw a picture wider than 16,384 pixels or larger than about 120 megapixels, so a huge JPG may not convert.
- Every finished picture is held in memory until you download it. PNGs are large, so do big folders in groups, especially on a phone.
Other conversions
Going the other way, to a smaller file? See PNG to JPG. Need .webp files opened? Use WebP to JPG. For iPhone photos, there are HEIC to JPG and HEIC to PNG, and the image converter reads many more types and also saves WebP.
Privacy
The conversion happens in this tab, and the files on your disk are never changed or deleted. For what the site collects, see our privacy policy.
Frequently asked questions
How do I convert JPG to PNG for free?
Drop your JPG files on this page and press Convert. Then download each file or the whole batch as a ZIP. Nothing needs to be installed and there are no settings to choose.
Does converting JPG to PNG improve the quality?
No. The PNG is an exact copy of the JPG as it looks now, including its flaws. The detail a JPG has lost cannot come back. What you gain is that the picture will not lose more when you edit and save it again.
Why is the PNG so much larger than the JPG?
PNG stores every pixel, while JPG stores an approximation. Our 155 KB test photograph became a 1,251 KB PNG, about eight times larger.
Can I make the background transparent by converting to PNG?
No: the conversion keeps the picture as it is, background included. To make the background see-through, use the background remover, which saves a PNG with transparency.
Does the PNG keep the EXIF data and the location?
No. The PNG is a fresh picture, so the camera details and GPS location stored in the JPG are not copied. The JPG is not changed, so you still have them there.
